Anion Gap Calculator
This calculator calculates anion gap from the stated laboratory values. Check the units and measurement conditions before interpreting anion gap.
Build the Anion Gap anion gap estimate
Before calculating Anion Gap
Collect sodium, chloride, bicarbonate for one clearly defined Anion Gap case.
- Sodium: Enter sodium. Keep its mmol/L with the anion gap.
- Chloride: Enter chloride. Keep its mmol/L with the anion gap.
- Bicarbonate: Enter bicarbonate. Keep its mmol/L with the anion gap.
Equation for Anion Gap
The Anion Gap method is anion gap without potassium. Comparing another result requires the same equation, units, and input definitions.
Interpreting Anion Gap anion gap
The Anion Gap result is an educational estimate, not a diagnosis or individualized professional advice.
Keep the Anion Gap entries and measurement date beside the output so its context is not lost.
Nearby questions are covered by Blood Pressure Mean Arterial Pressure, Estimated GFR, Vision Prescription Converter, Creatinine Clearance.
Checks for anion gap
- Confirm the units used for sodium, chloride, bicarbonate.
- Replace the Anion Gap demonstration values.
- Keep the source date with anion gap.
Keeping a useful Anion Gap record
Write down sodium, chloride, bicarbonate exactly as entered, including units and the date. For Anion Gap, an output without those details cannot be reproduced or fairly compared with a later result.
If circumstances change, preserve the first anion gap as a baseline and create a new run. This separates a real input change from rounding or memory.
Anion Gap example with stated units
A Anion Gap demonstration might begin with Sodium = 140 mmol/L, Chloride = 104 mmol/L, Bicarbonate = 24 mmol/L. Applying Na − (Cl + HCO₃) produces anion gap in the units displayed by the result panel.
Change one Anion Gap entry at a time when testing sensitivity; otherwise the reason for a different output becomes difficult to identify.
Where anion gap without potassium needs context for Anion Gap
The Anion Gap result is an educational estimate, not a diagnosis or individualized professional advice.
The Anion Gap method does not infer missing symptoms, laboratory conditions, device quality, reference populations, or professional judgment. Those details remain outside the arithmetic.
Reviewing Anion Gap before a decision
Recheck sodium, chloride, bicarbonate, confirm the named anion gap without potassium method is appropriate, and preserve the complete input record. A result that affects treatment, pregnancy, a child, or urgent symptoms needs qualified interpretation.
Anion Gap questions
Why does the Anion Gap result depend on these inputs?
The Anion Gap anion gap without potassium method uses sodium, chloride, bicarbonate; changing one changes the anion gap.
What method does Anion Gap use?
Anion Gap applies Na − (Cl + HCO₃), identified here as anion gap without potassium.
Are the Anion Gap examples personal recommendations?
No. The Anion Gap values for sodium, chloride, bicarbonate only demonstrate this calculator.
What should be saved with the Anion Gap result?
Keep sodium, chloride, bicarbonate, their units, the date, and the source for Anion Gap.
